QoS Classes

Pod QoS（Quality of Service）Classes是k8s根据pod的resource request/limit而设置的服务质量类，在节点资源不足时会根据QoS Classes进行驱逐

可选的QoS Classes有三种：Guaranteed、Burstable 和 BestEffort

<button class="headerButton">QoS Classes</button>	<button class="headerButton">条件</button>	<button class="headerButton">补充说明</button>
Guaranteed	Every Container in the Pod must have a memory limit and a memory request. For every Container in the Pod, the memory limit must equal the memory request. Every Container in the Pod must have a CPU limit and a CPU request. For every Container in the Pod, the CPU limit must equal the CPU request.	apply to init containers and app containers do not apply to Ephemeral containers
Burstable	The Pod does not meet the criteria for QoS class `Guaranteed`. At least one Container in the Pod has a memory or CPU request or limit.	If a limit is not specified, it defaults to a limit equivalent to the capacity of the Node
BestEffort	doesn't meet the criteria for either `Guaranteed` or Burstable 或者 none of the Containers in the Pod have a memory limit or a memory request none of the Containers in the Pod have a CPU limit or a CPU request Containers in a Pod can request other resources (not CPU or memory)	can use node resources that aren't specifically assigned to Pods in other QoS classes

<button class="headerButton">QoS Classes</button>

Guaranteed

Every Container in the Pod must have a memory limit and a memory request.
For every Container in the Pod, the memory limit must equal the memory request.
Every Container in the Pod must have a CPU limit and a CPU request.
For every Container in the Pod, the CPU limit must equal the CPU request.

apply to init containers and app containers
do not apply to Ephemeral containers

Burstable

The Pod does not meet the criteria for QoS class Guaranteed.
At least one Container in the Pod has a memory or CPU request or limit.

If a limit is not specified, it defaults to a limit equivalent to the capacity of the Node

BestEffort

doesn't meet the criteria for either Guaranteed or Burstable

或者

none of the Containers in the Pod have a memory limit or a memory request
none of the Containers in the Pod have a CPU limit or a CPU request
Containers in a Pod can request other resources (not CPU or memory)

can use node resources that aren't specifically assigned to Pods in other QoS classes
